3. Monitor & Reduce Gas Usage
- Use smart meters to track consumption in real-time.
- Conduct energy audits to identify waste.
- Train staff on energy-saving practices (e.g., turning off heating when not needed).
4. Consider Renewable Alternatives

- Hybrid heating systems – Combine gas boilers with heat pumps.
5. Negotiate with Suppliers
- Loyalty doesn’t always pay—ask for better rates when renewing.

When Should You Switch Gas Suppliers?
🔹 Contract is ending – Avoid auto-renewal at higher rates.
🔹 Prices have dropped – Check market trends.
🔹 Customer service is poor – Better suppliers offer smoother support.
